Well in the UK you can probably return it under your statutory rights. The game isn't doing what its supposed to be doing after all (i.e. its AI is certainly no challenge, even on hard with 7 "allied" computers against me all of which have a high bonus).

What would happen if the AI shared research? They can have "share research" treaties, however after an experiment I found that though I get the AI's tech, he doesn't get mine (even though it says he did). If that bug were fixed maybe the AI's really could ally together and share their research with each other.
Mind that still wouldn't help much if the AI's aren't bothering building research buildings in the first place.
